| 1 | Comparison of summer ther- mohaline field and circulation structure of the Bohai Sea between 1958 and 2000显示文摘The analysis of observed salinity data over 35 years (1961—1996) at four stations around the Bohai Sea, i.e. Huludao, Qinhuangdao, Tanggu and Beihuangcheng, reveals that the salinity of the 4 observation stations has increased 1.1, 1.6, 1.9 and 0.4, respectively. The data also show that over the past 35 years, there have been at least 5 large salin-ity variation processes. The salinity data from two cruises of the Bohai Sea in August 1958 and 2000, show that the salin-ity pattern of the Bohai Sea has changed markedly. Low sa-linity in the sea surface layer around the old Yellow River mouth in August 1958 had been replaced by high salinity in August 2000 and the maximum variation of salinity is over 10.0. In addition, the values and distribution of salinity were almost the same from surface to bottom there in August 2000, but there existed significantly different salinity levels be-tween the surface layer and the deep layer in August 1958. When a comparison is made between the salinity levels of the above-mentioned two years, it is found that the salinity in August 2000 is on average 2.0 higher than that of August 1958 in the main part of the Bohai Sea. The change of tem-perature and salinity field in the Bohai Sea leads to the change of the circulation. The numerical simulation shows that in comparison with the circulation structure of the Bohai Sea in August 1958, the circulation in August 2000 changes markedly. The significant changes of circulation appeared in Bohai Bay, Laizhou Bay and in the middle of the Bohai Sea. The clockwise current loop outside of the Bohai Bay and counterclockwise current loop outside of the Laizhou Bay in August 1958 disappeared in August 2000, and the counterclockwise current loop of the Bohai Bay mi-grated obviously outward. The flow direction in the Laizhou Bay turned 180° around. Corresponding to the variation of the Bohai Sea circulation, the amount of water exchange between the Bohai Sea and the Yellow Sea has also changed. The water exchange rate through the Bohai Strait decreases, on average, 0.7×104 m3/s in August 2000 in contrast to that of August 1958. | WUDexing WANXiuquan BAOXianwen MULin LANJian | 2004 | Chinese Science Bulletin2004，49，4： | 13 |
| 2 | THE INTRUSION AND INFLUENCES OF INTRASEASONAL LONG ROSSBY WAVES IN THE EAST CHINA SEA显示文摘The analysis of sea level data from tide stations and ocean general circulation model (OGCM) shows that the intraseasonal long Rossby wave results in the intraseasonal variations of Kuroshio axis and transport in the upper reaches of the Kuroshio in the East China Sea (ECS). Due to the transport modulation induced by Ryukyu Islands, the intraseasonal variation is very weak in the lower reaches of the Kuroshio in the ECS. A two-layer model reveals the relation among Kuroshio frontal unstable wave with topography, transport and the axis position of the Kuroshio, from which we can infer that the intrusion of intraseasonal long Rossby wave may stimulate the Kuroshio frontal unstable wave in the upper reaches of the Kuroshio in the ECS. The altimeter data also shows that the sea level anomaly resulting from intraseasonal long Rossby wave could pass the channel between Taiwan and Ryukyu Islands and propagate northeastward in accord with the Kuroshio frontal unstable wave. However, the sea level anomalies passing through the gaps of Ryukyu Islands are relative weak and have negligible effects on the Kuroshio variation. | LINXiao-pei WUDe-xing LANJian | 2004 | Journal of Hydrodynamics2004，16，5： | 5 |
| 3 | The interdecadal variation of Indonesian Throughflow and its mechanism显示文摘The interdecadal variation of the volume and heat transport of Indonesian Throughflow (ITF) and its mechanism are preliminarily studied on the basis of the up- dated SODA data. It is found that the interdecadal variation of ITF’s volume transport is mainly concentrated in upper 714 m and that of ITF’s heat transport is mainly confined to upper 450 m. There is fairly consistent interdecadal variation in the depth-integrated seawater pressure above different depths in the region south of Davao, north of New Guinea and southwest of Australia. The depth-integrated pressure difference between northwest of Australia and south of Java has best correspondence with ITF’s volume transport on interdecadal time scales. The relation between the wind stress on the Pacific and ITF’s volume transport on interde- cadal time scales is studied based on Island Rule. It is shown that both the wind stress along the zonal lines just south of Australia and the Equator act as the dominant contributors to ITF’s volume transport, with the latter dominating the phase of ITF’s interdecadal variation. These results indicate that the atmospheric forcing and oceanic adjustment in the tropical region both contribute significantly to the ITF’s interdecadal variation. | MENG WUDexing HURuijin LANJian | 2004 | Chinese Science Bulletin2004，49，19： | 3 |

| 5 | Photoluminescence from Ge-SiO_2 thin films and its mechanism显示文摘Ge-SiO2 thin films were deposited on p-type Si substrates using the radio frequency (rf) magnetron sputtering technique with a Ge-SiO2 composite target. Films were annealed in N2 ambience for 30 min at 300℃-1000℃ with an interval of 100℃. Through the X-ray diffraction, the average size of Ge nanocrystals (nc-Ge) was determined. They increased from 3.9 to 6.1 nm with increasing annealing temperature in the range of 600℃-1000℃. Under ultraviolet excitation, all samples emit a strong violet band centered at 396 nm. With the formation of nc-Ge, the samples exhibit another emission of orange band with the peak at 580 nm and its intensity increases with the increasing size of nc-Ge.The peak positions of two bands do not shift obviously. Experimental data indicate that the violet band comes from GeO defect and the orange band originates mainly from the luminescence centers at the interface between the nc-Ge and SiO2 matrix. | DONG Yemin, CHEN Jing, TANG Naiyun, YE Chunnuan, WU Xuemei, ZHUGE Lanjian & YAO Weiguo1.

| 8 | Influence of Al-doping on electroluminescence of silicon-based films显示文摘A series of Al-doped silicon-rich silica (AlSiO) composite films have been prepared by a dual ion beam co-sputtering method with a Al, Si and SiO2 composite target. The content of Al and Si in the films can be adjusted by changing the surface area of Al and Si of the target. Visible electroluminescence (EL) from the samples is found to have only one luminescence band peaked at 510 nm (2.4 eV). Experimental results show that the doping of Al is beneficial to reducing the onset voltage and to increasing the intensity of EL. | WU Xuemei YE Chunnuan ZHUGE Lanjian DONG Yemin TANG Naiyun YU Yuehui NING Zhaoyuan YAO Weiguo | 2001 | Chinese Science Bulletin2001，46，24： | 0 |
